I'm not sur if it is an issue from the game but I'd like to share it juste in case,
I had a game with a friend and I was posting a new message on our private league while we were searching each other with the matchmaking. Our teams joined each other and I was still writing the message. I just could not close the windows and I had to start the game with the big message in the middle of my screen. I attempted to close the game and restart it, I came to the main menu and I tried to re-join the game, but it crashed with graphic card report.
I tried this move 3 times but the report came instantly so I was forced to concede the game. I honestly don't think it comes from my hardware device. I might be wrong but maybe something may be fixed ?
Many thanks !
